The MUFIPs can break down the progression of the disease among overweight older Thais with knee osteoarthritis.

Being overweight is a major risk factor for developing knee osteoarthritis (OA). The purpose of the current study was to: (a) determine participant adherence to a quadriceps exercise and weight management program after completion of the intervention; and (b) examine whether a quadriceps exercise and weight management program can reduce knee pain and improve knee function and weight loss in 40 community-dwelling overweight Thai older adults with knee OA at 6- and 12-month follow up. Twenty-nine (76.3%) participants completed at least 75% of the program. Two (5%) participants did not complete the program. In the intervention group, significant improvement was noted in knee range of motion at 6 and 12 months compared with baseline, and a significant reduction was noted in knee pain, time spent in the Timed Up and Go test, and body weight compared with baseline. These study variables, except for body weight, between the intervention group and control group were significantly different. This study highlights the benefit of long-term adherence to the multicomponent intervention for community-dwelling overweight Thai older adults with knee OA.

Aim: To examine a causal model of health status among older people with knee osteoarthritis. Methods: A cross-sectional, correlational design was used with a convenience sample of 220 older Thai people with knee osteoarthritis (mean age 68.96 years; SD = 6.22). Participants were asked to complete a demographic questionnaire, the Pain Catastrophizing Scale, the Tampa Scale of Kinesiophobia, The Medical Outcomes Study Social Support Survey, and the Arthritis Impact Measurement Scales 2-Short Form. Structural Equation Model was used to examine a hypothesized model. Results: Using Chi-square, hypothesized model was statistically nonsignificant. A model of health status fitted with the empirical data and explained 19.2% of variance. Pain catastrophizing had negative direct effect on self-efficacy and health status. Pain catastrophizing also had negative indirect effect on health status through self-efficacy. Self-efficacy and social support had positive direct effects on health status. However, pain-related fear had no direct or indirect effect on health status. Conclusion: Lower level of pain catastrophizing can improve self-efficacy.
